<DIV><FONT face=Arial size=2>Hello All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am writing to report a problem that I have when
picking actors from a scene. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I built vtk 4.2 today and rebuilt an application
that I had designed with vtk 4.0. I am working in windows and I am using MSVC
6. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Once my geometry has been rendered to the
screen, I have a render window that contains multiple actors. The program
is designed in such a way, so that when an actor is picked, it is highlighted
by using a bounding box, it is made semi-transparent and some data
related to it are displayed at the point where the pick has been made
by using a vtkTextActor. This worked fine with vtk 4.0 but the not with
4.2. All actors in the render window appear at an incorrect depth order
and a confusing image appears. Actors that are supposed to be in the
back, covered by other actors, come in the front with the actor that has
been picked coming completely in the front (although it should not). After
I click on the screen again everything comes back to normal as the actor is
deselected. Text display and actor transparency work correctly though, as they
should.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Has anyone ever had such a problem in the past? Is
there a fix to that?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance for any help
provided.</FONT></DIV>
